In London, hundreds of people gathered Saturday on Trafalgar Square, protesting against the ongoing Hong Kong unrest.

Overseas Chinese have also held peaceful rallies against the violence in the French capital, Paris, and German cities of Berlin, Cologne and Hamburg.

Overseas Chinese and students in Britain sang the Chinese national anthem and chanted "no violence" and "one nation, one China".

The rally was organized after overseas students learned that some Hong Kong independence activists were planning a rally, said an overseas student.

He said they went there to express their support for Hong Kong and its police force, and their objection to separatists.

Meanwhile, around 3,000 people marched peacefully through the streets of Sydney Saturday to call for an end to the violence which has gripped the SAR in recent weeks.

Mobilized through social media, the Stop Riots in Hong Kong rally was predominantly made up of Chinese students. However, there was also a large number of local supporters in attendance as well.

Among banners reading "Protect Hong Kong, fight against violence," Tony Jiang, one of the group's leader who is an Australian citizen of Chinese descent, told Xinhua: "We came here to stand against the violent riots and the decaying law and order in Hong Kong."

Radical protesters in Hong Kong have abandoned their peaceful protests and unfortunately some of them have turned into violent mobs who smashed the parliament, ransacked the police stations and threw bricks and petrol bombs on the streets, Tony Jiang said.

"We support and we understand peaceful protest, but we believe it has grown into an out-of-control situation."

To show their solidarity with law enforcement officers in Hong Kong, many at Saturday's rally held up signs with messages of support for police.

Earlier on last Sunday, around 1,000 people from overseas Chinese communities in the Greater Toronto Area held a peaceful rally protesting against the violence in HKSAR.
